About Donsöhuvud Lighthouse

This square granite tower stands 29 meters tall on the southeastern point of Donsö island. Operational since 2023, it replaced a previous round lantern. The lighthouse features a drum-style Fresnel lens and emits a directional light with three flashes every 3 seconds, cycling through white, red, and green. Its focal height is 5 meters, providing a geographic range of 8.4 nautical miles. The tower is made of granite and is accessible to the public, though the tower itself is closed.

Why it matters: The light's directional, color-changing flash offers precise guidance through the Gothenburg archipelago's narrow channels and around the island's headlands.
